Also I doubt many apps, if any, will work right now. Since 2.0 is a new firmware and has only JUST been jailbroken, actually having it jailbroken at this time is nothing more than meaningless bragging rights. And since the jailbreak was only JUST released you're bound to run into a few hiccups. So just be patient and in probably a week or two you can do what you want without running as high of a risk of needing to restore due to an un-updated app.
